Remember last year's Viziv Concept? This is it's fit brother, that has been doing workout. Lots of workout. Featuring a sporty stance, it comes with all rings and bells of carbon fiber goodies, such as splitters, fender inserts and, an aggressive rear diffuser and a huge wing - hopefully this hints at the upcomming WRX STi - we just hope.

Infiniti came up with some teasers a few days ago, showcasing a sporty sedan, wearing their future design language.

It comes dressed as a four-door coupe styling and it might be their flagship model. The teaser allows us to see a shorter hood, proper space for passenger and an all-glass roof, which makes a continous glass line starting with the windshield, ending with the rear window.

Earlier this week, Mercedes has just announced their new sports saloon, C63. You probably noticed we used AMG C63 in the title, that's because Benz decided to kill the previous nomenclature.

"We are marking the beginning of a new era with the new nomenclature. The successor to the Mercedes-Benz C63 AMG, which has been incredibly successful worldwide, will now be called the Mercedes-AMG C63" says Tobias Moers, CEO of Mercedes-AMG GmbH.

Following the WRX launch in November 2013, enthusiasts all over the world were waiting for this and yes, Subaru didn't let us down, they have worked on the STi version of the WRX.

And boy it's not a letdown, the photos show us what we expected, a hotter WRX version, painted in World Rally Blue matched with golden alloy wheels and the massive rear spoiler, which admited or not, it is a statement.

There are no tech specs released, but the STI is rumored to get a larger 2.5-liter turbocharged four-banger with 300 bhp (224 kW) and 290 lb-ft (393 Nm).

Ladies and gents, it is official, the new M models have been revealed and we're talking about new M3 which is a sedan and the former M3 has turned into M4 which is a coupe (future cabrio).

The beasts are being powered by a straight 6 cylinder, 3L, twin turbo engine, which develops 431HP and 406Nm torque. Weight has been saved from everything, starting with the engine (80kg), CFRP roof 5kg for the Sedan and more than 6km from the Coupe.
